Does a CDN affect search rankings?
-
I feel kind of stupid asking this, but if i use one it would speed things up quite a bit. It is for a ecommerce website, any guidance on this would be awesome!
-
Google officially said the site speed is a SEO factor which, when implemented, will affect 1% of SERP results. This gives some idea of the scope of it's relevancy. (not saying 1% is either high or low, this is all very subjective)
Having said that, beyond speed improvement, CDN provides other SEO related benefits.
I've actually just published a 2-part Blog post that investigates SEO & CDN related myths and talks about CDN and SEO benefits, I hope you`ll find it useful. it should answer all questions:
Part 1: SEO & CDN Myths
Part 2: SEO & CDN benefits -
I use a CDN and have never seen any impact on my SEO. As long as your HTML is served off your domain you're fine.
If you're using AWS Cloudfront you can set up a CNAME so that your content comes from, say, images.mydomain.com instead of xyz.cdn.com. Helps obscure it from visitors and looks a bit neater.
-
Using a properly configured CDN will not have any negative effects on SEO. It can have positive effects on your rankings by offering faster page loads.
With Google's current system, you would not see a SEO benefit per se. If your current site is deemed slow by Google, you could have your current speed penalty lifted.
Moving to a CDN will surely provide a better user experience. Google is constantly adjusting it's algorithms in chase of the best user experience, so this is a chance for you to get ahead of the game. It is reasonable to think in the future Google may consider site speed as a ranking factor.
Two other suggestions regarding setting up a CDN:
-
you need to be very conscious of your cache settings. You could make a change on your site and users will not see the change if you do not ensure that change is propagated throughout your CDN
-
try to include all files which would benefit from a CDN. I have seen some sites just add their videos and image files to the CDN. Custom Javascript, CSS files and so forth can all benefit from CDN. PageSpeed and YSlow are two great tools for optimizing page loading times.
-
-
As far as I know, the urls of your additional resources such as images, css, and scripts shouldn't affect your SEO either way.
-
But, does the use of a Content Delivery Network (cdn) itself affect seo? For example my pics / code will be hosted differently. Just kind of confusing to me since I'm used to URL structure being: mydomain.com/images/pic.jpg instead of xyz.cdn.com/2523/myname/pic.jpg. Is this even something to be concerned about?
-
Site speed is only relevant when your site is extremely slow. Google doesn't penalize you unless your page load time is excessively long. You won't get a boost in rankings by speeding up your site.
With that in mind, Site load times do affect your user experience, so you may notice a lower bounce rate, more pages per visit, and possibly a higher conversion rate.

Page Rank Flow
I wonder if someone can help me understand clearly page rank flow. If we have a website with a Home page, Services, About and Contact as a very basic website and the page rank will flow to each of those pages from the Home page (i'm not including internal linking between pages or anchor text from the home page content - this is a question purely about home page flow via the main navigation). If the Services page had 3 drop down pages. Would the home page rank also flow to each of these or is it going to the Services page which then distributes it to the three drop down. So instead of Home page rank flowing to 3 pages 33% each - it is flowing to 6 pages 16.6% each. Or is it flowing to 3 pages - 33.3% then the Services pages get a third of 33.3% ->10.1% I know this is simplifying it all a great deal- but it is the basic concept I am trying to grasp on this simple example. Thanks

Google Search Console Not Sending Messages
One of our sites received a Manual Penalty for unnatural links by Google. However, we never received a message in Google Search Console or an email about the manual action. The only reason we knew about the penalty is by the obvious drop in rankings, then signing into search console to look for any manual actions, which we found. Since then, we have submitted a disavow file and a reconsideration request. However, once again we did not receive an email or message in search console that shows confirmation of the disavow or that they received the reconsideration request. The disavow file does show up after I upload it, and it says it was successfully uploaded... but no messages or emails. After many hours of investigating the various canonical versions of our website on Search Console, we found out that there were several “owners” of the various canonical versions of our site that had “could not find the email address” as a site owner. We found out that these were previous employees who no longer worked with the company and their email address was deleted. After unverifying these site owners, (all the ones that had “could not find the email address” as the site owner), the notifications, emails and messages in Search Console started to appear. However, the only place they did not appear, is the main canonical version of our site. Of course, the main canonical version of our site (https://www) is the version that we uploaded the disavow and reconsideration request. This is the canonical version of the site that we need to receive these messages to know if our reconsideration request was granted! We’ve just reuploaded the disavow file and reconsideration request to all of the other canonical versions (2 of the 3 received the message about the penalty)…. and we are currently awaiting a response. Has anybody else had problems with not receiving notifications in search console due to deleted email addresses?

Wordpress versus html and google ranking
My current SEO has always recommended that I take my site to wordpress. I really don't want to move to wordpress. I don't like it... I just like writing code in raw html, css, and script. I feel like I have more control that way. Wordpress just seems like a platform for blogs (I have my blog in wordpress). My question is, do wordpress websites typically rank better? Is there benefit to moving to it?

Notice of DMCA removal from Google Search
Dear Mozer's Today I get from Google Webmaster tools a "Notice of DMCA removal" I'll paste here the note to get your opinions "Hello, Google has been notified, according to the terms of the Digital Millennium Copyright Act (DMCA), that some of your materials allegedly infringe upon the copyrights of others. The URLs of the allegedly infringing materials may be found at the end of this message. The affected URLs are listed below: http://www.freesharewaredepot.com/productpages/Ultimate_Spelling__038119.asp" So I perform these steps: 1. Remove the page from the site (now it gives 404). 2. Remove it from database (no listed on directory, sitemap.xml and RSS) 3. I fill the "Google Content Removed Notification form" detailing the removal of the page. My question is now I have to do any other task, such as fill a site reconsideration, or only I have to wait. Thank you for your help. Claudio

How to Resolve Rankings Drop from a DDOS Attack?
Our rankings just plummeted on Tuesday across the board. There was a DDOS attack on Tuesday and since then the rankings went down and have stayed down, even though the DDOS attack has been resolved. Also, this is the 3rd or 4th attack they've encountered this year. How long could this last? How can we deal with this? Thanks

How long does it take for rank to return after 301?
Hello all -- just looking for those who have implemented site-wide 301 redirects due to a domain change. I am about 2 weeks into mine and am seeing minimum 5, maximum 21 spot drops in many of my targeted terms. My pages have strong GPR, with most being 3 or higher. Anyone out there been able to track a ballpark of when rank will return? The 301 redirects were implemented correctly, with 1 to 1 setups in most cases. Google has updated the listings with the new domain name, but I'm taking a huge rank hit. Any experience on how long I can expect (I know it's different for every situation) would be great! Thanks.
